Even in BC, you can still use cases from other provinces in your advocacy.
A key finding in this case as you will see below is: that a parent’s “fierce advocacy” for his or her child must not and cannot prevent a school board from accommodating the child’s needs to the point of undue hardship.“
From the case:
 The Interim Decision sets out my reasons for issuing an order with respect to the first two points, as follows:
(a) School boards have an obligation under the Code to accommodate their students with disabilities to the point of undue hardship, regardless of whether the students are receiving any medical treatment in the community or not;
(b) School boards cannot order or demand of parents to place their children into residential psychiatric treatment programs and cannot deny or withhold accommodations to the point of undue hardship on the grounds that the student should be in such a program. While I have no evidence to show that this was the case here, that does not alter the principle;
(c) School boards have an obligation under the Education Act to provide appropriate special education placements, programs and services to their exceptional students. Parental conduct or lack of parental authority cannot be used as a justification for not meeting an exceptional student’s needs; and
(d) I agree with the decision in R.B. v. Keewatin-Patricia District School Board, (R.B./Keewatin) 2013 HRTO 1436, an HRTO decision cited by both parties in this case, at para 265, that a parent’s “fierce advocacy” for his or her child must not and cannot prevent a school board from accommodating the child’s needs to the point of undue hardship.
